Sorry, don't take it personally, sometimes I take a long time to answer the comments, you see I have a regular job and therefore I have a pretty tight schedule, so I'm dedicating all my free time to the game and sometimes I don't have time to see the comments.
well regarding your ideas:
1) most of the creatures you described will be in future updates.
2) the game will have multiple endings, these will vary depending on certain decisions of the player and the level of degeneration that Eve has for that moment.
3) Eve will act in a more lascivious way the higher her degeneration level is, but this is a feature that I will exploit more in future updates, although I will keep that last suggestion of yours in mind ;)
I'm glad you liked the game, and thank you very much for sharing your ideas. ;)
I wish you a nice day.
